World's Scariest Borders

Colombia + Panama

The jungle between Panama and Colombia, known as the Darien Gap, is a nearly impassible territory of undeveloped forests and swamps that’s ruled by guerilla and paramilitary groups. It’s just as well that no proper roads run through it. There’s barely more than a path fit for a rugged motorcycle or well-armed off-road vehicle. Sane people enter Colombia via air or from Panama City to Cartagena by boat.
